Abstract: Disclosed is a method for thermally drying pasty products, in particular wastewater sludge, and a belt dryer implementing such a method. The principle consists of partitioning the drying operations and using, for each of the successive operations, a different quality of air: (i) hot air for “searing” the sludge, (ii) low temperature air, then (iii) cold air for quenching the sludge before the extraction of same. Also proposed are loops of air supply circuits making it possible to optimize the energy consumption of the dryer by reusing energy produced within these circuits. Moreover, the loops make it possible to recover unavoidable low temperature energy or cheap energy, further optimising the consumption of the dryer.

Abstract: Disclosed is a method for heating a biomass moving along an industrial treatment line including an inlet (91) for the incoming biomass, a pressure pump (93), a heating unit (94) and a treatment station (95). According to an embodiment, steam is injected into the line between the pressure pump (93) and the heating unit (94) such as to pre-heat the biomass by condensing the steam.

Abstract: Disclosed is a method for heating a biomass moving along an industrial treatment line including an inlet (1) for the incoming biomass, a heating unit (4), and a treatment station (5). A fraction of the biomass heated by the heating unit (4) is returned along a return branch (R) to a mixing station (2) upstream of the heating unit (4) so as to form, together with the incoming biomass, a mixture having a temperature above the temperature of the incoming biomass, the heated biomass fraction being removed at an outlet (51) of the treatment station (5).

Abstract: A method of continuous hydrothermal carbonization of sludge containing organic matter involves a step of hydrothermal reaction carried out in a reactor, and at least one cooling step in which the sludge having undergone the hydrothermal reaction step is cooled. The hydrothermal reaction step includes: a step of injection of sludge in which the sludge is injected into the reactor by a first inlet; a step of injection of steam in which steam is injected into the reactor by a second inlet, the second inlet being distinct from the first inlet; a step of circulation, in which a mixture consisting of the sludge and the steam injected into the reactor is placed in circulation within the reactor; a step of continuous extraction of at least a portion of the mixture contained in the reactor by a sludge outlet. Also disclosed is a device for carrying out such a method.

Abstract: Disclosed is a piston press of the type used in the field of the dehydration of products to be dehydrated such as sludge from a purification plant. More particularly, it relates to a piston press including a pressing chamber supplied with sludge and able to manage air streams that it generates, and to a method for using such a press. In a preferred mode of embodiment, the piston press includes a pipeline having a water removal branch and arranged so as to remove water extracted during a sludge-pressing operation, and an air circulation branch that can channel the volumes of air circulating in the press during the operation thereof, so as to direct the vitiated air, i.e. air that has been brought into contact with the sludge during the implementation of the press, towards a deodorization system.

Abstract: A method of continuous hydrothermal carbonization of sludge containing organic matter, involving a stage of hydrothermal reaction carried out in a reactor (4), includes: a step of introduction of sludge in which the sludge is introduced into the reactor (4) by a first inlet (11), a step of endogenous injection of steam in which steam is injected into the reactor (4) by a second inlet (15) distinct from the first inlet (11), a step of extraction in which at least a portion of the sludge contained in the reactor (4) is extracted continuously by a sludge outlet (16), a step of preheating in which the temperature of the sludge is raised prior to its introduction into the reactor (4) up to a temperature of preheating greater than 70° C. Also disclosed is a device making it possible to carry out such a method.

Abstract: The present invention relates to the field of heat treatment of a product to be dehydrated, such as sludge from a waste water treatment process. The present invention relates more particularly to a method and to a facility for drying such a product, making it possible to implement a hydrothermal carbonization operation on reactor 1 followed by a filtering and drying operation, preferably on a heating filter press 6. In order to dry said product in the heating filter press 6, a heat-transfer fluid from a heat exchanger 2 is made to flow in said heating filter press. The heat exchanger 2 is arranged so as to transfer, to the heat-transfer fluid, at least some of the heat contained in the product to be dehydrated that is output from the reactor 1.
